[R] Upgrading R means I lose my packages

[ONKELINX, Thierry]

On a windows machine you get the same problem. Useless one uses tha same
trick as Rolf suggested: don't install the packages in the default
directory and set R_LIBS to that directory. Then all you need to do
after an upgrade is to set R_LIBS in the new version and run
update.package(checkBuilt = TRUE). Given Rolf's suggestion I suppose
this trick will work on a Mac too.

HTH,

Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

The plural of anecdote is not data.

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.

	I'm not sure --- I find Mac OS very confusing.  But I have the 
***impression*** that
	(on my system) by default packages get installed into

		~/Library/R/2.7/library

	i.e. into a library inside the directory tree rooted in my login

directory.

	I don't use this --- I've created my own library ~/Rlib and have
	set up an environment variable to point to it.

	(This works properly only if you start R from the command line;
for
	reasons I don't understand if you start R by clicking on the
icon
	then R doesn't know about the R_LIBS environment variable.  But
since
	all civilized people start R from the command line .....)

	I have no idea why youse guys' systems would eschew using
~/Library/
<whatever>.
